Site factors are the wider environmental and human features of the landscape which influenced the locations of our settlements.

Defence - against surrounding tribes this was sometimes necessary. Good defensive sites may have been within a river meander, with the river giving protection on three sides like Durham. Sometimes settlements were built on hills or steep slopes to give commanding views like Edinburgh

Shelter - in Britain it is an advantage to be sheltered from the strong prevailing south-westerly and cold northerly winds

Aspect - the direction a face slopes. A south facing slope will be warmer as this faces the sun.
Nodal Points - this is where several routes meet to create a route centre like York
Gap towns - these are settlements which developed in the flat land between two higher pieces of land
